CAMPBELL (Archibald), third Duke of Argyle, brother to the subject of the preceding article, was born at Hamhouse, in England, in June 1682, and was educated at the University of Glasgow. He afterwards applied himself to the study of the law at Utrecht; but, upon his father's being created a Duke, he betook himself to a military life, and served some time under the duke of Marlborough. Upon quitting the army, in which he did not long remain, he applied to the acquisition of that knowledge which would enable him to make a figure in the political world. In 1705, he was constituted treasurer of Scotland, and made a considerable figure in Parliament, though he was not more than twenty-three years of age. In 1706, he was appointed one of the commissioners for treating of the Union; and the same year was created Lord Ormsay, Dunoon, and Arrois, Viscount and Earl of Illay. In 1708, he was made an extraordinary Lord of Session; and when the Union was effected, he was chosen one of the Sixteen Peers for Scotland, in the first Parliament of Great Britain; and was constantly elected to every future Parliament till his death, except the fourth. In 1710, he was made Justice-General of Scotland. In 1711, he was called to the privy council; and upon the accession of George I. he was nominated lord register of Scotland. When the rebellion broke out in 1715, he again betook himself to arms, in defence of the house of Hanover, and by his prudent conduct in the West Highlands, he prevented General Gordon, at the head of three thousand men, from penetrating into the country, and raising levies. He afterwards joined his brother at Stirling, and was wounded at the battle of Dumblain. In 1725, he was appointed keeper of the privy seal; and, from this time, he was entrusted with the management of Scottish affairs. In 1734, upon his resigning the privy seal, he was made keeper of the great seal, which office he enjoyed till his death. Upon the decease of his brother, he became duke of Argyle, hereditary justice general, lieutenant, sheriff, and commissary of Argyleshire and the Western Isles, hereditary great master of the household, hereditary keeper of Dunstaffnage, Carrick, and several other castles. He was also chancellor of the University of Aberdeen; and laboured to promote the interest of that, as well as of the other universities of Scotland. He particularly encouraged the school of physic at Edinburgh, which has now acquired so high a reputation. Having the chief management of Scotch affairs, he was also extremely attentive to promote the trade, manufactures, and improvements of his country. It was by his advice that, after the rebellion in 1745, the Highlanders were employed in the royal army. He was a man of great endowments both natural and acquired, well versed in the laws of his country, and pos-
essed considerable parliamentary abilities. He was likewise eminent for his skill in human nature, had great talents for conversation, and had collected one of the most valuable private libraries in Great Britain. He built himself a very magnificent seat at Inverary. The faculties of his mind continued found and vigorous till his death, which happened suddenly on the 15th of April 1761, in the 79th year of his age. He was married, but had no issue; and was succeeded in his titles and the estates of the family by John Campbell, fourth duke of Argyle, son of the honourable John Campbell of Mammore, who was the second son of Archibald the ninth earl of Argyle.
The family of Argyle was heritable justice-general for Scotland till abolished by the jurisdiction act. They are still heritable masters of the king's household in Scotland, and keepers of Dunstaffnage and Carrick.
